Because it does not make any sense.
I obviously don't understand your position that "it does not make
any sense" -- perhaps you could explain a bit?
What I see is a suspension point that is waiting for the results of
coro(), which will be negated (and returned/assigned/whatever).
What part of that doesn't make sense?
Because you want operators to be resolved in the
order you see them, generally.
You want '(await -fut)' to:
1. Suspend on fut;
2. Get the result;
3. Negate it.
This is a non-obvious thing. I would myself interpret it
as:
1. Get fut.__neg__();
2. await on it.
So I want to make this syntactically incorrect:
'await -fut' would throw a SyntaxError. To do what you
want, write a pythonic '- await fut'.
